EXAMPLES FOR ACTIVE 2-WAY APPLICATIONS
Fig. 3
Fig. 3 shows the possibility of how to achieve even higher SPL through employing an additional FX 20 woofer and Mid/Hi cabinets on each side of the stage. Additional cabinets are simply connected in parallel to the existing speaker systems. Of course, configuring woofers in a left-center-right setup – as outlines in Fig. 2 – is possible without problem. Stacking the Mid/Hi cabinets on top of each other almost doubles coverage, without the drawback of too high acoustic output in the proximity of the stage. Using the “stack & splay” technique
–turning the stacked Mid/Hi cabinets so that they aim at slightly different angles – even improves coverage of the audience area.
Fig. 4
Fig. 4 shows a setup consisting of a complete Xa standard installation per side, which is especially suitable for major clubs and large festival tents up to a size of approximately 3000 sqm. If needed, this configuration allows expanding each Xa system through adding additional loudspeaker cabinets (please refer to Fig. 3).
The left-center-right setup delivers noticeably more SPL in the low-frequency range and most of all provides truly homogeneous dispersion and coverage in the audience area, without the annoyance of interference. This configuration is particularly recommendable for wide stages.
